Decision making, process and logic through which individuals arrive at a decision. Different models of decision making lead to dramatically different analyses and predictions. Decision-making theories range from objective rational decision making, which assumes that individuals will make the same decisions given the same information and preferences, to the more subjective logic of appropriateness, which assumes that specific institutional and organizational contexts matter in the decisions that individuals make.

Rational decision making

In modern Western societies the most common understanding of decision making is that it is rational—self-interested, purposeful, and efficient. During rational decision making, individuals will survey alternatives, evaluate consequences from each alternative, and finally do what they believe has the best consequences for themselves. The keys to a decision are the quality of information about alternatives and individual preferences. Modern economics is built on this understanding of how individuals make decisions.

Rational decision making becomes efficient when information is maximized and preferences are satisfied using the minimum of resources. In modern societies, rational decision making can occur in markets or firms. Both assume that individuals will act rationally, maximizing self-interest, but each works most efficiently under different conditions. Markets are most efficient when both buyers and sellers exist, when products or services are discrete so that the exchange can be one-time, when information about a product or service (such as its technology or means of evaluation) is broadly understood, and when there are enforced penalties for cheating.

Lacking these conditions, consensual exchange cannot occur, and rational individuals will try to cheat others to maximize their gain. In these cases a hierarchical organization is more efficient. The German sociologist Max Weber described how factories and bureaucracies became dramatically more efficient through growing technical expertise and, more importantly, a new division of labour, which divided work, specialized expertise, and coordinated individuals in a rule-based hierarchy. Bureaucracies decomposed complex technologies into manageable pieces, then allowed individuals to specialize and master a defined skill set. Using a clear hierarchy in which each position is controlled and supervised according to a stable and nonarbitrary system of rules, each individual’s work and expertise could be coordinated to achieve organizational goals, ranging from winning wars to making dresses.

Satisficing and bounded rationality

In the 1940s, organization theorists began to challenge two assumptions necessary for rational decision making to occur, both of which were made obvious in cases where markets failed and hierarchies were necessary. First, information is never perfect, and individuals always make decisions based on imperfect information. Second, individuals do not evaluate all possible alternatives before making a choice. This behaviour is directly related to the costs of gathering information, because information becomes progressively more difficult and costly to gather. Instead of choosing the best alternative possible, individuals actually choose the first satisfactory alternative they find. The American social scientist Herbert Simon labeled this process “satisficing” and concluded that human decision making could at best exhibit bounded rationality. Although objective rationality leads to only one possible rational conclusion, satisficing can lead to many rational conclusions, depending upon the information available and the imagination of the decision maker.

Simon argued that otherwise irrational individuals can behave rationally in the right context, particularly within a formal organization. Organizations can structure, or bound, individuals’ decisions by manipulating the premises on which decisions are made. Organizations can filter or emphasize information, bringing facts to an individual’s attention and identifying certain facts as important and legitimate. Individuals in hierarchies can take most of what happens around them for granted, concentrating only on a few key decisions. Hierarchies are efficient because they ensure that the correct information gets to the correct decision makers and that the correct person is making the decisions. At the same time, hierarchical organizations can socialize individuals to refrain from cheating by creating value decision premises that underlie decision makers’ judgments on what is right or good to do. These values, beliefs, or norms can come from family, from school, or from within the organization, but the organization can structure environments so that the most desirable value will be most salient at the time of decision.

Hierarchical organizations can structure factual and value decision premises so that the range of action becomes so narrow that only one alternative remains: the rational choice. Structuring decision premises can be done by directly managing information, selectively recruiting members, training members, and creating closed promotion patterns.

Organizations become rational in pursuing their missions through what Simon called ends-means chains. Leaders set the organizational mission, find a set of means for achieving the mission, take each of those means as a subgoal, and then find means for the subgoals and so on, until goals exist for every member of the organization. Leaders thus create a hierarchy of goals, in which each organizational level’s goals are an end relative to the levels below it and a means relative to the levels above it. Each individual’s work thus becomes a small part of accomplishing the organization’s mission.

Intra-organizational political decision making

Turning Simon’s bounded rationality on its head, other theorists argued that organizations are not purposeful cohesive actors but rather groups of competing coalitions made up of individuals with disparate interests. Individuals do not represent organizational interests; organizations represent individuals’ interests. Seen from this perspective, it is erroneous to ascribe a mission to an organization. Instead, organizations have goals set by a temporarily dominant coalition, which itself has no permanent goals and whose membership is subject to change. Members of the dominant coalition make decisions by bargaining, negotiating, and making side payments. Organizational decision making is the product of the game rather than a rational, goal-oriented process. Individual decision making is rational in the narrow sense that individuals pursue individual, self-interested goals, though this cannot always be accomplished directly. Individuals must pick their fights and use their influence carefully.

To understand and possibly predict what organizations will do, it is necessary to uncover and analyze the membership of the dominant coalition. The formal organizational chart is not a reliable map of organizational power. Instead, analysts must discover authority. Individuals gain authority by being able to resolve uncertainty. Individuals that can unravel technical problems, attract resources, or manage internal conflict demonstrate their usefulness to the rest of the organization and gain power. Working in concert with others who can perform similarly valuable functions, they become part of the dominant coalition. The size and composition of the dominant coalition depend on the types of environmental, technical, or coordinating uncertainty that must be resolved for the organization to survive. More technically complex, larger organizations in rapidly changing environments will tend to have larger dominant coalitions.

For rational decision making to occur, an individual must gather information and analyze potential choices by devising alternate and complete sets of ends-means goals for all members of the organization. If a single individual cannot do this, then the leadership must complete this planning function so an organization can be rational. Leaders must create logical ends-means chains, as well as set out clear subgoals supported by appropriate factual and normative premises. Some scholars believe this task to be impossible. No group, they argue, no matter how clever or technically competent, can create subgoals and coordinate efforts at a place like IBM or the New York public school system. The contexts and environments change too quickly, the technology is too complicated and contingent, and the organizations are too large and unwieldy for leaders to effectively imagine and evaluate complete alternative plans of action for the entire organization.

If overall coordination and top-down guidance is impossible, then how do regular members make decisions? According to some organizational theorists, individuals faced with change will tend to continue doing what they already know how to do. Decisions are repetitive and similar because the guide to future action is past action. Bureaucrats are content to use the same procedures and forms, comfortable in their routines. If that regular behaviour produces a result that they perceive as failure, individuals will adjust to avoid the failure. Change is reactive and incremental. In cases where feedback to individuals lags or no feedback exists at all, change may never occur. Bureaucracies exhibit incredible inertia, and reform is a mammoth undertaking, usually with modest results.

Other organization theorists explained in more theoretical detail why individuals will tend to repeat decisions and follow routines. They argued that humans make sense of the world by using routines that frame experiences to make them intelligible. These informal routines absorb uncertainty, making it possible for humans to function by allowing them to focus on just a few important decisions. Formal organizations, especially hierarchical organizations, exaggerate this tendency toward routine and use it to achieve organizational rationality. As Simon noted, organizations focus individuals’ attention and decompose complex tasks and problems so that one person can handle them. Practically speaking, organizations accomplish this by creating standard operating procedures. Although standard operating procedures allow individuals to function and cooperate at a high level, they also create the organizational inertia that Charles Lindblom noted. Routines put blinders on individuals, absorbing uncertainty but also reducing the information they receive and perceive. Routines—particularly, formal routines such as standard operating procedures—often become disconnected from the actual requirements of the job at hand and even from individuals’ immediate self-interest, because individuals become so accustomed and dependent on their routines that they literally cannot imagine doing without them. What used to be rational decision making becomes irrational in new circumstances.

Appropriate decision making

Moving to the opposite end of the theoretical spectrum from rational decision making, a more sociological approach emphasizes social context over economic rationality as the key to decision making. According to the logic of appropriateness, individuals consider their situation, evaluate their role in that situation, weigh actions according to their appropriateness, and finally do what is appropriate. Rational decision making assumes that individuals will act to maximize their preferences and engage in self-interested behaviour, but the logic of appropriateness assumes that individuals will conform to external rules—norms, routines, procedures, and roles—often without consciously realizing that they are making a decision. Individuals tend to do the right thing.

Appropriate decision making emphasizes the fit between the context, especially social norms and roles, and individuals’ perceptions, especially their self-perceptions. Behaviour follows from how individuals fit the nested contexts and roles they inhabit. Predicting behaviour is complicated because individuals inhabit many, many contexts and many roles. In any given situation, an individual must decide, even if subconsciously, which of several competing roles and related rules to apply. The key criterion is how appropriate the rule is to the situation.

James G. March and Johan P. Olsen showed how the logic of appropriateness inverts the causal logic of rational decision making. Individuals form opinions and make decisions to be appropriate in their surroundings, to fit in with those around them. This means that context precedes preference, and social interaction is more important than abstract self-interest. Instead of liking those we trust, we trust those we like. Instead of choosing our friends on the basis of what they value (“I like Carolyn because we both voted Democrat”), we choose our values to match with those we like (“I voted Democrat because I like Carolyn and she voted Democrat”). Of course, all decisions cannot be socially appropriate, and all preferences are not socially derived. But the first cause is social, rather than innate preference. Timing is important. Social contexts matter more when preferences are weak, as in childhood, or shaken, as during a crisis. Behaviours and structures will tend to replicate themselves as new members are socialized and internalize the preferences, values, norms, beliefs, and ideas of those around them.

Temporal decision making

Finally, some scholars studying organizations and observing real decision making saw so much disorder and randomness that they came to believe there is little consequential, logical order to decision making. Instead, they saw temporal order. Studying universities, they found problems, solutions, decision makers, and choice opportunities coming together as the result of being simultaneously available. Timing is key. Decisions are produced by happy accidents, when all the necessary ingredients can be combined.

In what has been called “garbage can processes,” problems, solutions, opportunities, and decision makers swirl around independent of each other within organized anarchies, which act only to contain them. Organizations are organized anarchies when they have problematic preferences, unclear technology, and fluid participation. In other words, in organized anarchies, members are unclear and inconsistent about what they want to do, how they are supposed to do it, and who should make which decisions. As a result, people, solutions, and problems are independent, and a decision is only made when the four are connected by timing and attention. Attention is the key resource, because most decisions are left unmade because no one is paying attention. Solutions search for problems, as people with pet ideas wait for the opportunity to spring them.

Evaluating decision-making models

Some models are more appropriate to certain situations than to others. Universities will tend to be “garbage cans,” but armies will tend to be rational hierarchies. The nature of the task, the technology, the personnel, and the context provide clues about what type of decision making will occur. The more specific the goal, the better understood the technology, the less professionalized the personnel, and the more stable the context, the more likely that rational decision making will occur.

However, the different models reflect different fundamental assumptions about human interaction and behaviour. Each has strengths and weaknesses. Rational decision making is an elegant and powerful model. But it also fails to accurately describe almost all actual decision making. Tinkering with it to accommodate psychology or politics makes it more realistic, but the model also loses elegance and analytic power, producing more description than prediction. The logic of appropriateness and temporal sorting may have the most intuitive appeal, but systematically applying them can be difficult, and producing confident predictions is nearly impossible.

Decision-making models have real implications for strategy and policy making. For example, arguments for school vouchers in education rest on the assumption that parents are rational decision makers and will choose to send their children to the best schools. If Simon is right and they are satisficers, however, parents need substantial assistance with researching and evaluating schools if they are to make rational choices. If parents actually use logic of appropriateness, the experts’ opinion of the best schools will not matter as much as their friends’ and neighbours’ opinions, which may have more to do with the basketball team or location than academics. Finally, if parents simply follow routines or are not paying attention, they will do nothing, because they will not receive any penalty for not exercising school choice, and the vouchers will only benefit those who are already paying attention, such as parents who send their children to private schools or homeschool their children.
